Description

Integrated type solar water heater system

About solar collector, the particularly invention of domestic solar water heater system.

Widely used solar water heater, specific product is the form of absorber or heat collecting element mostly and arranges whole consistent, easily manufactured, (utilizing optically focused can improve output temperature improves properties of product but fail to make full use of the grade of direct light and the enrichment of diffused light; Utilize air preheat that the heat energy cost is declined to a great extent).In fact, various solar energy heat collectors still remain to be developed.

The objective of the invention is to provide that a kind of heat waste is littler, output temperature and the thermal efficiency more Gao Bingke satisfy solar energy heat collector, particularly the domestic solar water heater system that needs usefulness in severe winter.

The object of the present invention is achieved like this: adopt its height isothermal segment to place the inconsistent heat insulation or heat collecting element of quality middle and that adapt than the absorber of marginal position or employing and water route or gas circuit each several part condition of different temperatures or characteristic to make heat collector respectively, and with accumulation of heat or heat-exchanging part and go here and there in water route or gas circuit manually or autocontrol valve, the fuzzy control valve that particularly the control accuracy error is bigger is formed water-heater system and various solar energy heat collector, configurable external reflector when needing, air preheater, sunshine tracking or governor motion, the antifreeze device of anti-overflow, elevated tank, orientation is sent the water intake pipe, mode of operation switching mechanism and auxiliary heater.

The present invention adopts the low temperature thermal-arrest is partly surrounded high-temperature part and senior middle school's low-temperature device appropriate combination is passed through printing opacity thermal insulation layer and peripheral photo-thermal loss to reduce heat collector; Use external reflector and air preheater can increase heat supply to heat collector; External reflector can also effectively improve the thermal efficiency, output temperature and to the utilization rate of winter, morning and evening and faint sunlight; Adopt fuzzy control and orientation to send the water water intaking can realize best heat-collection heat-supply; The auxiliary electrically heated round-the-clock system of band is convenient and reliable and single with coal, electric than every m ²900 kilowatts of System economize on coal every year 1 ton and saving of labor 200 hours or when economizing on electricity.

Accompanying drawing 1 provides one embodiment of the present of invention.This is one and is with the right side of the dull and stereotyped water heater of integrated form direct current of reflector to look and face, also does to install and structural representation.Among the figure, housing 1 frame is lived septum pellucidum hot body 2, and the water route that interior dress shows by arrow and dotted line 3 is from outer dish inside tube plate absorber 4 and heat-insulating material.The highest part of absorber 4 temperature is arranged horizontally and is in the heat collector middle part near the elongate body 7 of the outer reflector 5 one side bands of the little condensing body of one dimension to upper overturning 6 and selective absorbing film; Flange 6 can be caught more reverberation; The fuzzy control valve that design temperature is 50 ± 20 ℃ can and be loaded on elongate body 7 back with the light moulding pipe manufacturer of a free end of bimetal leaf; For a long time for reverberation shines upon, made the valve open of back in case be heated by the elongate body 7 of emphasis heat insulation (comprise and add one deck printing opacity thermal insulation layer) and leading portion absorber (oblique line shows) thereof, hot water just is pressed into attemperater.Enter after the stable state, water inlet is that absorber progressively heats and exports along the water route; The inclination angle of reflector 5 can be adjusted with sunshine tracking or governor motion 8.Reflector 5 also can place the top or need not; Also can post luxuriant and rich with fragrance lens and come optically focused at absorber maximum temperature place; One section tube plate absorber air preheater of water inlet guest performer can effectively improve collecting efficiency in the higher occasion of temperature; The diagram water heater can be formed collector system with attemperater.Make the water source with running water or elevated tank, place the outer also height of balcony to put attemperater water heater and can make fully-automatic household solar energy shower system; In water tank, install by the normally open valve that can close water into and one can connect float-type micro valve group mode of operation switching mechanism that attemperater bottom and the normally close valve of heat collector import form can be when water tank will be expired automatically (also can other use manual switchover) DC mode is switched to circulation pattern, vice versa; Replace tube plate absorber and discharge water to make vexed solarization of integrated form or half vexed solarization water heater with disc type cassette bulk absorption body with automatic or manual; Post sunset can be cut off the water supply water heater and be used device 9 water-drainage antifreezings of using as pneumatic vacuum flask of calming the anger that are communicated with the water heater conduit by valve again severe winter.

All-weather water heater system's electrical auxiliary heater adopts temperature control or adopts the multikilowatt primary heater of a band timer and hectowatt grade secondary heater is incubated or preheating, particularly straight-flow system control the delayed start-up secondary heater further to economize on electricity with cistern water level and convenient the use.

As the straight-flow system model machine of Fig. 1, daylighting 1m ²Add 0.5m ²Reflector gross weight 23kg.In the snowfield in January of Shanghai, 2 hours noons, water temperature reached 70 ℃, obtained 45 ℃ of hot water 45kg in 6 hours altogether.

Accompanying drawing 2 provides an alternative embodiment of the invention.This is one and adopts the right side of the integrated form medium-temperature collectors of multiple element partly to cut open and face.Among the figure, housing 1 frame is lived septum pellucidum thermosphere 2, these 3 parts of disc type tube plate absorber 3(can) the fluid passage serial connection band that shows by arrow and dotted line 4 focuses on reflector 5, it is heat insulation and with the tubulose heat collecting element 6,7 and the 8 composition integrated form calandrias of glass-tube and vacuum heat-insulation to be respectively sensitive surface.The highest exportable heat energy more than 100 ℃ of this class device.

Accompanying drawing 3 shows: when luminous power such as curve 1, the Fuzzy control system of tool characteristic 2 can obtain than have characteristic 3 and 4 liang of system's gained sum more thermal energy and after a period of time the hot water temperature of first system the highest.(luminous power is system's heat-collecting capacity to the time integral of valve open).

Accompanying drawing 4 has been described an improvement of the present invention.This is the structure chart of an attemperater.The water deceleration heats to be with the vertical float valve 2 that floats bar 1 to make into the water storage increase among the figure; The high temperature water inlet divided and delivers to eminence in water tank 6 low during one end come-up band can will hang down the directed flow pipe 5 of (bimetal leaf) cold water bypass valve 3 of cold water bypass (with the cold water introduction pipe) and 4; Being made up of the suction hose 9 of inlet tube and

outlet tube

7 and 8 and one end come-up has the directed intake pipe 10 that sprays swabbing action, when the water storage upper heat and lower cold, as go out water flow velocity slowly then cold water through water inlet pipe 7 outflows; When flow velocity is fast then the valve 11 in water inlet pipe 7 outsides close because of pressure reduction and in the double action that suction hose 9 outlet is shunk for the sensing element (bimetal leaf) 12 of the hot water heating of flowing out hot water flowed out.(it is adiabatic that orientation send the water intake pipe to answer)
